T0 all whom, it may concern:

Be it known that I, RoBERrP. SOHILLING, a citizen of the UnitedStates,residing at Berkley, in the county of Norfolk and State ofVirginia, have invented certain new and useful Improvements inCoin-Controlled Vending- Machines, of which the following is aspecification, reference being had therein to the accompanying drawings.

The invention relates to coin controlled vending-machines, and hasparticular refer= ence to a device of this character designed andadapted to dispense liquids.

The inventionconsists in the peculiar construction of thevending-machine and in the novel combination and arrangement of itsvarious parts, as will be more fully hereinafter described and shown. Inthe drawings, Figure 1 is a vertical central section, partly inelevation, through the machine detached from the casing. Fig. 2 is aside elevation, partly in section,of the mechanism, showing fragments ofthe casing at tached thereto. Fig. 3 isa cross-section taken on line a;as, Fig. 2. Fig. at is a side elevation of the machine as in use. Fig. 5is a vertical central section through the measuring-cup. Fig. 6 is aperspective View of the coin-actuating mechanism and the operatingdevice therefor; and Fig. 7 is a section on line y y, Fig. 3.

A is an inclosing casing having an entering-slot B formed therein, asshown. I a

A designates a receptacle within the casing into which the liquid isstored, the receptacle being in the form of a measuring-cup providedwith suitable valve-controlled inlet and outlet ports hereinafterdescribed.

B designates the casing of the outlet-valve connected to the threadednipple Gupon the measuring-cup, and D represents the inlet-' valvecasing, which is connected to and communicates with the casing B througha suitable connecting'pipe E.

F is a discharging device in the form of a spout, consisting of atubular member G, fixed to the lower end of the valve-casing 13,1 andamovable'telescoping member H, mount ed upon the stationary member forvertical reciprocation. The members are normally separated by means of acoil-spring I, which abuts at its upper end against a flanged ring J,secured to the stationary member, and at its lower end against the upperportion of the nozzle K.

L represents the outlet-valve, which bears normally against its seat M,and O is a valvestem extending upwardly Within the casing.

P represents a coil-spring encircling the valve-stem adapted to bearagainst a stop 0. upon the latter and the valve-casing and acting tonormally hold the valve to its seat.

Extending within the stationary member of the discharge-spout is thestem I), carried by the valve just described.

0 is a slot formed in the side of the upper tube or spout member,through which an arm d of a bell-crank levereextends. This lever ispivoted at the junction of its arm to a bracket-arm a, secured to thespout. The

inwardly-extending lever-arm is connected in constructed as to deliver acoin upon said shelf between the arm f of the bell-crank le- 7 ver andthe member G of the discharge-spout.

Within the valve-casing D is arranged the ivalve U, provided with a stemV, connected through a yielding link g and a spring h to an arm 2',extending outwardly from the angle-plate S. The yielding link comprises,es-

. It acts normally to hold the valve U away from its seat 0, so as toallow the inletto the measuring-cup to be normally open. The connectionbetween this valve and the operating device of the mechanism, which inthis case is preferably the reciprocating member of the discharge-spout,is the bell-crank lever to, pivoted upon the bracket-arma. One arm pof this lever projects past the yielding link and beneaththe pin q, secured to the socket, while the other armr extends in aparallel direction with the discharge-spout and is held constantly incontact with said spout through the agency of the spring h.

After the coin has been inserted within the machine and the deviceoperated in the manner that will be hereinafter set forth the coin isautomatically deposited into a box or coinchamber X. The automatic meanswhich I employ for this purpose is of the following construction:

Y represents a roll journaled at its ends in the angle-plate S and abracket-arm Z.

r is a pin fixed upon the upperpart of the roll adapted to engage themember R of the shelf, so that upon the movement of the roll in eitherdirection the shelf will be actuated.

s designates a spring-actuated pin arranged within a recess t in theroll, the spring being fixed within said recess to prevent the pin frombeing moved entirely out of the latter. The pin last described extendsnormally within the path of the tapered head 0 upon the member H of thedischarge-spout.

The liquid that is to be dispensed is supplied to the apparatus throughthe valve-controlled inlet-port, before referred to, in any suitablemanner, necessarily under pressure when the source of supply is locatedbeneath the machine. The liquid is free to pass normally into themeasuring-cup, and the air within the cup is forced out through thevalvecontrolled venttube a The measuringreceptacle consists,essentially, of the cup proper, 12 in which is arranged a pistonhead 0.

(1 design ates a hollow piston-stem, which is provided with a head 6swiveled within the piston, and extends outwardly from the cup through astuffing-box 7L2 and to and through a threaded tubular bearing fsupported upon the frame g At the upper end the pistonstem is providedwith an operating handle or knob i and is also threaded, as at j wherebythe piston may be raised or lowered to determine the quantity of liquidthat is to be dispensed.

7c designates a valve for the hollow stem (1 Z is a tubular stem forthis valve, extending within the hollow stem referred to, and isprovided at the end thereof with a head m 0 designates a springinterposed between this head and a shoulderp upon the stem (1*, thespring acting to maintain the valve normally against its seat.

(1 represents a threaded rod the upper end of which has a threadedengagement within the valve 75 and its stem, while the lower end isconnected to the stem of the valve L, the latter connection beingpreferably a lost-motion connection of any well-known and suitable type,so as to insure the proper closing of both valves. The thread upon therod g is of the same pitch as the thread upon the hollow piston-stem,and the valve is connected to the head 6 by means of a suitable bolt 6.This bolt permits vertical movement, but prevents rotary movement, ofthe valve 76 relatively to the head 6".

It will be seen from the above construction that the capacity of themeasuring-cup may be varied at will by simply turning theoperating-handle and that the shifting of the piston to effect thisvariation will not in any way interfere with the action of theinlet-valves.

The parts of the mechanism having been thus described, the operation ofthe machine is as follows: A coin isinscrted within the entering-slot inthe casing and is delivered by the chute upon the shelf in such manneras to form a coupling between the leverfand the operating device. Theoperator then moves the section H upwardly until the tapering orinclined head thereon engages the lever-arm 7', which actuates the valveU, closing the inletport to the receptacle. Upon further movement of thespout-section the head thereon forces in the pin .9 within the rolleruntil the head passes by the latter, when the pin is released andengages beneath the head. Still further movement upward of thespout-section causes the inclined head to bear against the coin, whichforces out the lever-arm f, opening the outlet-valve and the valve 70Air is thus enabled to enter through the pistonstem into themeasuring-cup,and the fluid that is to be dispensed passes down throughthe discharge-spout and into the glass or similar receptacle which isheld beneath the same. After the contents of the receptacle have beenemptied the glass is withdrawn from beneath the spout and the latter isreturned, by means of the coil-spring, to its normal position. Theshoulder a upon the head upon the downward movement of the spout-sectionengages the pin .9, which revolves the roller and forces the shelf frombeneath the coin, allowing the latter to drop into the chamber ormoney-box before referred to. The shelf is automatically returned to itsnormal position by means of a spring 11 which is connected to the rollerand the angle-plate. The discharge of the coin from the coin-pocketdescribed allows the outlet-valve of the apparatus to automaticallyclose, and the passage of the head out of engagement with the lever-arm7' permits the inlet-valve to be automatically opened. The

IIO

fluid from the source of supply then enters the measuring-cup throughthe inlet-port, and the air in said cup is forced out through theair-vent a controlled by a float-valve a In order that the operatingdevice of the mechanismviz., the reciprocative spoutmay be readilyactuated, I have provided a lip c for the nozzle portion K, againstwhich the glass is adapted to bear when raising the spout. Also I haveprovided a strainer (l for the movable spout-section in order that theliquid that is dispensed may be free from impurities. The strainerreferred to is in the form of a tubular netting closed at one end,

which is adapted to be inserted within the movable section and which isprovided wit-h a head a, which has a threaded engagement with theinterior portion of the nozzle K.
